Runes is simple puzzle game.
Idea is simple, match 3 or more pieces of the same kind to turn them into 1 higher rank element. At beggining game will look easy, but as soon as you get more elements on gamefield, it will get harder and harder, forcing you to think about every move.
Game includes highscores and achievements. Enjoy.
